Yochanan III 1:3

3 For I had simcha gedola (much joy) when the Achim b’Moshiach arrived [here] and gave eidus (testimony) of you being in HaEmes (the Truth), just as your walk is halakhah b’Derech Emes (conduct in the Way of Truth).

Yochanan III 1:3 Meaning and Commentary

3 John 1:3

For I rejoiced greatly when the brethren came
From the place where Gaius lived, to that where John now resided; these brethren seem to be preachers of the word, who travelled from place to place to spread the Gospel:

and testified of the truth that is in thee;
either of Christ, who was formed in him; or of the Gospel, which had a place in his heart; or of the truth of grace that was in him, as well as of that faithfulness, integrity, and sincerity he appeared to be possessed of, being an Israelite indeed, and without guile:

even as thou walkest in the truth:
in Christ, and in the Gospel, and as became it, and with all uprightness; see ( 2 John 1:4 ) ; and this occasioned great joy in the apostle; as it is matter of joy to every one that truly loves Christ, and his Gospel; or has the true grace of charity in him, which envies not the gifts and graces of others, but rejoiceth in the truth, wherever it is found; and especially to the faithful ministers of the word, when they hear of the truth of grace in any souls, and that such continue walking in the truth of the Gospel, and particularly those who have been wrought upon under their ministry, as follows.

Yochanan III 1:3 In-Context

1 From the Zaken (Elder, SHEMOT 3:16). To Gaius HaAhuv (Gaius the beloved), for whom I have ahavah (agape) b’Emes.

2 Chaver, it is my tefillah that all may be hatzlocha (successful) with you, and that you may be shalem b’guf (healthy), just as your nefesh (soul) is matsli’ach (successful).

3 For I had simcha gedola (much joy) when the Achim b’Moshiach arrived [here] and gave eidus (testimony) of you being in HaEmes (the Truth), just as your walk is halakhah b’Derech Emes (conduct in the Way of Truth).

4 I have no greater simcha than this, to hear of my bnei b’Moshiach, that their walk is halakhah b’Derech Emes.

5 Chaver, you do a thing of emunah (faith) when it is done for the Achim b’Moshiach [engaged in the Shlichus (Divine Mission) of Messianic Kiruv Rechokim itineration in the kehillot], especially when they are people you don’t know.
